Over the years many improvements have been made to heating, air conditioners, air exchanger's, evacuation fans and the like. Efficiency has been a great priority as has been the quality of the air we breathe. Very little has been done to utilize nature itself as our ally it has rather dealt with it as an adversary. My system changes all that, nature gives us cool nights during the hot weather and nice days during the cold seasons- this is wasted energy which my system will harness.
